FUEL-IGNITER FOR GRATES.

Specification of Letters Patent. Patented Apr. 16, 191 8 Application filed March 23, 1917. Serial No. 156,879.

To all whom it may concern:

Be it known that I, GUY It. IVILLIAMs, a citizen of the United States, residing at San Francisco, county of San Francisco, State of California, have invented new and useful Improvements in Fuel-Igniters for Grates, of which the following is a description.

In getting a fire started in stoves or other fuel burners difliculty is experienced in get-- ting such fuels as coal, to start to burn, it being customary to lay the fire first by placing the coal upon a bed of more readily combustible material, as for example, shavings and Wood or paper and wood. When this more combustible material is lighted its combustion establishes the necessary heat to ignite the coal.

In my igniter, I employ under the grate a form of gas burner which may be adjusted and controlled from outside, and by the use of which, the use of any paper or wood or any easily combustible substance is obviatedby the gas flame produced from my igniter, after which the gas is shut off and combustion proceeds as usual. I prefer to displace the igniter with reference to the fuel grate after ignition although this is not necessary, except for the better protection of the mechanical structure of the igniter and grate.

Reference to the accompanying drawing will make clear the structure and operation of my igniter.

Figure 1 shows in plan the preferred structure of the igniter with the grate bars removed and with the connections to the gas pipe.

Fig. 2 shows in section the igniter in place in the fire box.

Fig. 3 shows a plan of the igniter to larger scale.

Fig. 4: shows a plan of the grate and a method of shifting the same.

Fig. 5 shows an assembled view of the igniter, grate and fire box.

Similar letters refer to similar parts in the drawings.

a, a is a tubular member, built up of tubes or pipes or may be cast hollow: It is formed with axial trunnions on which it may be partially rotated as at b b. This rotation may be effected through suitable lever connections at 0 or c not shown and too-well known to require further description. I prefer to form 0 as a square proj ection so that it may readily be engaged by a standard form of wrench. Axially mounted at one end is a gas injector c supplied with gas from the main 9 and under the control of the valve 7". Air may be admitted at d.

The tubular member is provided with a plurality of holesz', suitably located, and there is thus obtained a number of Bunsen flames from these holes when the igniter is lighted. To facilitate the lighting of the igniter I prefer to arrange a pilot as at a, under control of the cock n. It is to be noted that the member. a, a swings about the trunnions b, 1) although the gas connections e, f, g, n, a are stationary. The member a, a is provided with lugs h to better support and limit the movement of the grate. The grate k 70 j j is provided with a lug Z, which when the grate is horizontal, engages with the member m, and by which the grate may be moved back and forth over the igniter.

The method of operation is as follows Coal or other fuel to be ignited is placed upon the grate bars k 70, and the handle m being previously pressed in, the holes 2', i, in the igniter are exposed directly under the fuel tobe ignited, gas is now turned on at n and f and is ignited by the pilot light a. The burning gas under the fuel will quickly, uniformly, and effectively ignite the entire exposed area, after which the gas I is turned off and the grate moved by pulling the member at outward, thus covering the holes 5,2, in the igniter with the bars 7, mechanically protecting them from burning or plugging. Although this relative displacement is herein shown as accomplished by moving the grate it will be obvious that there are numerous other ways of causing it.

For the purpose of cleaning; the entire igniter and grate may be partially rotated on trunnions b I) thus enabling the ashes and cinders to be dumped and to facilitate this and also to secure the stability of the assembled parts when in use, the axis may be displaced upward with respect to the grate and bars, although this is not an essential of my invention.

Having thus described my invention, I claim 1. An igniter for stoves and the like, congas connections and adapted to burn gas under the fuel contained in the grate.

2. An igniter for stoves and the like, consisting of a gas member rotatably mounted and adapted to support a grate, a grate movable thereon, said member provided with gas connections and adapted to burn said gas under the fuel contained in the grate, and external means for causing said rotation of the gas member and said movement of grate.

3. An igniter for stoves, and the like, hav ing a plurality of gas outlets in combination With a movable grate having thereon members adapted to cover said outlets When in one position and to expose them When moved to another position.

a. An igniter for stoves, and the like, having a plurality of gas outlets in combination With a movable grate having thereon members adapted to cover said outlets when in one position and to expose them When moved to another position, in combination with a separate gas injector for lighting from the outside of the stove the gas escaping from said outlets.

5. An igniter for stoves, and the like, con sisting of a gas member rotatably mounted and adapted to support a grate, a grate movable thereon, said member provided With gas connections and adapted to burn said gas under the fuel contained in the grate, and a pilot flame connection to light the issuing gas from the outside of the stove.
